GEARING FC R WASHING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 7 50,243, dated January19, 1904:.

Application filed July 31, 1903. Serial No. 167,729. (No model.)

To all whom it may concern.-

Be it known that I, FREDERICK T. BROSI,

a citizen of the United States, residing at Quincy, in the county ofAdams and State of Illinois, haveinvented certain new and usefulImprovements in Gearing for Washing-Machines, of which the following isa specification, reference being had therein to the accompanyingdrawings.

My invention relates to power-transmitting mechanism of that type whichis employed for converting a rotarymovement in a single direction intoan oscillatory movement; and one of the primary objects thereof is toprovide such mechanism which will be compact, inexpensive, and durableand which is particularly adaptable for driving the agitator ofawashing-machine from an ordinary driveshaft having constant rotarymovement in one direction.

To this end the invention includes the combination and arrangement ofcomponent parts and the details of construction to be herein' afterdescribed, and particularly pointed out in.

the claims.

While the invention is susceptible of vari-.

line 5 5 of Fig. 4, and Fig. 6 is, a detail view.

The invention includes generally a driveshaft carrying a pinion, adriven shaft, and a pair of horizontally-disposed racks connected attheir ends by substantially right-angularlyextending portions orcontinuations thereof to provide in connection with the first racks onepractically continuous elliptical rack with which the pinion referred tointermeshes.

As premised, my invention is designed particularly to be embodied in awashing-machine, and I have shown the same in the ac companying drawingsin this association.

Fig. 4 is a transverse The drive-shaft (designated by the letter a) isshown as journaled in suitable bearings formed in a bracket 6, which isbolted to the top or cover 0 of the washing-machine, and the drivenshaft, which is indicated by the letter d, is shown asvertically-disposed, extending axially through the cover and carrying atits lower end an agitator e.

Fixedupon the shaft 01 is a hub f, from which the rack mechanism issupported so as to be capable of partaking of a tilting movement. Thismechanism includes in the present exemplification of my invention twohorizotallydisposed rack-sections g h, each curved to form part of acomplete circle concentric to the shaft d, the adjacent ends of whichare connected by vertically disposed continuations or end sections whichform, with the sec tions g h, a complete elliptical track.

Upon the inner end of the shaft a a pinion z' is fixed, which worksbetween the racks g h and is of slightly less diameter than the distancebetween the same, and consequently when in mesh with one of said rackssaid pinion runs free of the other. To retain the pinion in operativeconnection continuously with the endless rack, so as to drive the shaft(Z constantly during the rotation of the shaft a, means are provided forcontrolling the position thereof. This means preferably comprises aprojection is, extending axially from the pinion, coacting with aguideway m in the rack-frame. This guideway is preferably formed by aring n, interposed between the body portions 9 and h of the tworack-sections, to which said body portions are bolted with interposedspacinglugs. The spaces formed by said lugs between the upper and lowersides of the ring and the edges of the body portions of the adjacentrack-sections constitutethe horizontal portions of the guideway, and thevertical portion connecting said horizontal portions to provide anelliptical guide parallel with the elliptical rack is formed by recesses0 in the periphery of said ring. The two rack-sections g h and theintegral end continuations thereof are each cast in one piece with thebody portion referred to and constitute, in combination with the ringdescribed, what might be termed the rack mechanism. As

premised, this mechanism is supported from the hub f in such a mannerthat it may tilt as the pinion reaches the ends of the elliptical track.In the present exemplification of my invention the supporting meansreferred to include a ring p, arranged within and concentric with thefirst ring, pivoted to the hub at diametrically opposite points 1 '1'and pivoted to the first ring at diametrically opposite points s s aquarter-turn from the pivotal connections r r. In the operation of themech anism, assuming that the pinion is in mesh with the upper rack gand the shaft (4 is rotating in the direction indicated by the arrow,the shaft (7 will be tilted in the direction indicated by the arrowuntil the end portion 75 of the rack comes into mesh with the pinion,when the entire rack mechanism will be lifted and the pinion in thecontin ucd rotation of the same will mesh with the rack IL. Thedirection of rotation of the shaft (Z will then be reversed, and uponthe pinion coming into mesh with the end a of the rack or end portion ofthe continuous rack the entire rack mechanism will be depressed and thepinion will reengage with the teeth of the rack g.

The shaft (1, hereinbefore described, is driven from a shaft 11, havinga hand-operating wheel y. For transmitting the rotation of the shaft11', which finds bearings in suitable brackets secured to the tank ofthe machine, a pair of pinions :11 are employed, which are fixed to theshafts a m, respectively, and said pinions are. consequently separatedeach time the cover is thrown back and automatically reengaged upon thecover being closed, the pinion a when in operative position restingdirectly upon the pinion w. The pinions are housed in a sectional casingw, one section of which is carried by the cover and constitutes apart ofthe bracket 7), while the other section of the casing is carried by thetank.

The construction and operation of my invention will be understood uponreference to the foregoing description and accompanying drawings, and itwill be appreciated that the arrangement and combination of partsrecited maybe varied within a wide range without departing from thespirit and scope thereof.

Having thus described my invention, what is claimed as new, and desiredto be .secured by Letters Patent, is

1. In transmitting mechanism and in combination, a drive-shaft, a drivenshaft, rack mechanism comprising parallel sections and end-connectingportions, a hub on the driven shaft, supporting means interposed betweenthe same and the rack mechanism to permit of the tilting of the latter,and a pinion carried by the drive-shaft coacting with the rack,substantially as described.

2. In transmitting mechanism and in combination, a drive-shaft, a drivenshaft, rack mechanism comprising parallel sections and end-connectingportions, a hub on the driven shaft, supporting means interposed betweenthe same and the rack mechanism to permit of the tilting of the latter,including a ring pivoted to the hub and to the rack mechanism, and apinion fixed to the drive-shaft, substantially as described.

3. In transmitting mechanism for converting a rotary movement in onedirection into an oscillatory movement and in combination, adrive-shaft, a driven shaft, rack mechanism including two horizontallydisposed rackbodies carrying rack-sections curved in a horizontal plane,and end continuations curved in substantially vertical planes, aringinterposed between said body portions and separated a distance therefromto provide a guideway, a hub on the driven shaft, a second ringarrangedin the first concentric therewith, pivots diametrically arranged forconnecting the rings, other pivots diametrically arranged for connectinga second ring to the hub, and a pinion mounted on the drive-shaft,substantially as described.
